[PATCH 6/6] hw/arm: add Quanta GSZ bmc machine |
|
Date: |
Thu, 7 Nov 2024 19:54:53 +0000 |
This patch adds the quanta-gsz-bmc target, a current Google machine of
the day. This machine will be used as a platform to enable features such
as the PECI bmc interface, and Intel eSPI virtual wire interface in
QEMU.
